When corticotropin-release factor (CRF) travels from the hypothalamus to the pituitary, the pituitary releases the body's adrenocorticotrophic hormone (ACTH). The bloodstream carries ACTH to the adrenal gland and various other organs. This example illustrates the complex relationship between:.

Explanation:

When corticotropin-release factor (CRF) travels from the hypothalamus to the pituitary, the pituitary releases the body's adrenocorticotrophic hormone (ACTH). The bloodstream carries ACTH to the adrenal gland and various other organs. This example illustrates the complex relationship between the central nervous system and the endocrine system.

The hypothalamus is part of the nervous system and it is located in the forebrain below the thalamus. The major function of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. The interaction of the hypothalamus, the pituitary gland and the adrenal gland to release hormones is an example of how the nervous system (hypothalamus) is linked to the endocrine system (pituitary gland).
